Participants were selected using multistage sampling. Psychological well-being was assessed using the Warwick–Edinburgh Mental Well-Being Scale. Family-related predictors included family cohesion and family support; peer-related predictors included peer support and friendship quality; school-related predictors included school connectedness, academic engagement, and academic standing; and individual predictors included self-esteem, resilience, emotion regulation difficulties, perceived stress, and selected demographic characteristics. An artificial neural network based on a multilayer perceptron architecture was developed using 70% of the sample for training, 15% for validation, and 15% for independent testing. Model performance was evaluated using mean squared error, root mean squared error, mean absolute error, correlation coefficients, and coefficient of determination. Permutation-based feature importance was used to rank predictors.</p> <p><strong>Findings:</strong> The artificial neural network demonstrated strong predictive performance, with R² values of .83, .76, and .74 in the training, validation, and test samples, respectively. In the independent test sample, the model achieved R = .86, RMSE = 4.44, MAE = 3.52, and MSE = 19.74. Perceived stress was the most influential predictor, followed by self-esteem, resilience, emotion regulation difficulties, family support, and school connectedness.</p> </td> </tr> </tbody> </table> <p><strong>Conclusion:</strong> Psychological well-being among adolescents can be predicted with substantial accuracy using a multidimensional artificial neural network model, with individual psychological resources and stress-related factors contributing most strongly while family and school contexts also providing meaningful predictive value.</p> https://journals.kmanpub.com/index.php/jayps/article/download/6218/11804
